# GaussianSplatResource.SphericalHarmonicDegree

Spherical harmonic (SH) coefficients encode view-dependent color information. Higher degrees produce higher frequency variance at the cost of additional data per splat:

## Declaration

```swift
enum SphericalHarmonicDegree
```

## Overview

Overview Zero — 3 values (diffuse color only) First — 12 total values (3 new lobes + level zero diffuse) Second — 27 total values (5 new lobes + level one SHs) Third — 48 total values (7 new lobes + level two SHs)
